Can anyone think of a location where an arena is located next to a 50K football stadium in a suburban situation?
The one that occurs to me is Hamburg where the football ground is right next to the Colorline Arena (or whatever they call it now). Their arena is smaller though than the one planned for East Manchester..
The difference is that Hamburg's arena is served by a heavy rail line and also two S-Bahn lines so it works fairly well from what I understand. I went to an event at the Arena some years ago but it wasn't during the football season. They must be used to clashes though because they use it for ice hockey (or they did)
